State the Angle Relationship & Find the measure of the indicated angle that makes lines u and v parallel.

the indicated angle should be 121°

Step-by-step explanation:

If 2 lines are parallel to each other & a transversal intersects both of them , the corresponding angles on a same side are equal.

If the indicated angle will be equal to the given angle , they will be known as corresponding angles only when v || u.

So the indicated angle is 121°

m∠a is 90°

m∠b is 40°
